In order to make selection methods more efficient and to make improvement works perfect in developing new mustard cultivars at the Agricultural Research Station in Lovrin, we carried out a series of research and biometrical measurements starting from the necessity of better knowing specific variability, quantitative features, productivity features, the way they are passed on hereditarily, and the intensity of the correlations between them.Yielding capacity is a complex quantity feature based on a large number of elements relying on numerous genes with small effects. In developing mustard cultivars, the improver should get and use information on the heredity of the features for all the components in order to guide hybrid generations towards a genetic constitution able of improving production. [5].
Heritability studies have determined quantitative genetic variability made mustard and nature of gene action affecting the production and main components of the production. [1].They studied a number of quantitative characters including the number of seeds per plant. Compared with the parental forms most hybrids have achieved higher values for seed weight per plant.For seeds per plant weight resulted in an increase overdominant this character first generation hybrids, namely whether the reduction of F2 hybrids. At genitors study, there was a higher proportion of dominant alleles (60-70%) involved in genetic determinism of character study, based on a uneven distribution of positive and negative alleles.In terms of the proportion of dominant or recessive alleles they possess, is positive or negative parental forms were classified into distinct groups. These differences were due to the action of environmental factors that have led to different groups of genes that have the main role in controlling the characters studied event. |
